BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to quinazoline and quinoline derivatives, a method of their preparation, and a method of using the same as pharmaceutical agents.

2. Description of the Related Art

Protein tyrosine kinases (PTKs) modulate a wide variety of cellular events, including differentiation, growth, metabolism, and apoptosis. Transmembrane receptor tyrosine kinases (RTKs), members of the PTK family, are the high affinity cell surface receptors for many polypeptide growth factors, cytokines and hormones.

The mechanisms by which most RTKs transmit signals are now well established. Binding of ligand results in the dimerization of receptor monomers followed by transphosphorylation of tyrosine residues within the cytoplasmic domains of the receptors. However, mutations in the transmembrane (TM) domains of RTKs have been implicated in the induction of pathological phenotypes. These mutations are believed to stabilize the RTK dimers, and thus promote unregulated signaling without ligand binding.

Overexpression of PTK in cells can cause weak signals to be amplified. Furthermore, during many steps of cellular signal transfer, the occurrence of mutations or overexpression of PTK can cause false signals. These false signals play a role in carcinogenesis.

Epidermal growth factor receptor (EGFR) is one of the typical examples. EGFR belongs to cell surface receptors of epidermal growth factor receptor tyrosine kinase (EGFR-TK). The receptor family comprises EGF receptor (a protein product of oncogene erbB-1), erbB-2 (c-neu or HER2) receptor, tumor protein mutant erbB-3 receptor, and erbB-4 receptor. EGF and transforming growth factor alpha (TGFα) are the two most important ligands of EGFR. Though the receptor plays a minor role in healthy adults, it is closely related to the pathological process of most cancers, particularly to colon cancer and breast cancer. Therefore, an EGFR-TK inhibitor that can block the transfer of these receptor signals can be used to treat cancers caused by EGFR overexpression, such as colorectal cancer, breast cancer, kidney cancer, lung cancer, and head and neck cancer.

An EGFR-TK inhibitor can also be used to treat other diseases caused by EGFR overexpression, such as psoriasis, nephritis and pancreatitis which are described below.

Conventional treatments for proliferative skin diseases such as psoriasis include anti-cancer drugs, such as methotrexate. However, methotrexate has strong side effects and response is poor within the necessary limited dosage. In psoriatic tissues, TGFα is the main growth factor that is overexpressed. In animal experiments, 50% of transgenic mice with TGFα overexpression produce psoriasis, which suggests that a good inhibitor of EGFR signal transfer mechanism may inhibit psoriasis, i.e., the EGFR-TK inhibitor can relieve psoriasis symptoms.

EGF is an important epithelial mitogen and plays a role in renal tubular cell replication. In streptozotocin-induced diabetic mice, secretion of urine and mRNA of EGF are increased fourfold. Additionally, the expression of EGFR is enhanced in patients with proliferative glomerulonephritis (Roy-Chaudhury et al., Pathology, 1993, 25, 327-332). These findings indicate blocking EGF signal transfer can be used to treat and prevent renal injury. Therefore, it is postulated that an EGFR-TK inhibitor could be used to treat proliferative glomerulonephritis and renal disease induced by diabetes.

It has been reported that in chronic pancreatitis patients the expression of EGFR and TGFα is much higher than in healthy adults (Korc et al., Gut, 1994, 35, 1468). The overexpression of erbB-2 receptor has been confirmed in patients with severe chronic pancreatitis (Friess et al., Ann. Surg., 1994, 220, 183). Therefore, it is postulated that an EGFR-TK inhibitor could potentially be used to treat pancreatitis.

During embryonic cell maturation, embryonic cell implantation in endometrium, and other peripheral implantation, EGF and TGFα are present in uterine tissues (Taga, Nippon Sanka Fujinka Gakkai Zasshi, 1992, 44, 939) and EGFR levels are increased (Brown et al., Endocrinology, 1989, 124, 2882). Meanwhile, heparin-binding EGF (HB-EGF) is expressed in the uterus in a blastocyst-mediated process. (Das et al, Development, 1994, 120, 1071). TGFα and EGFR are highly expressed in embryonic cells (Adamson, Mol. Reprod. Dev., 1990, 27, 16). Surgical removal the submandibular gland and treatment with monoclonal antibody against EGFR can greatly reduce the fertility of mice by decreasing the success of embryonic cell implantation (Tsutsumi et al., J. Endocrinology, 1993, 138, 437). These results indicate that an EGFR-TK inhibitor may function as a contraceptive.

WO1992/007844 and WO1992/014716 disclose 2,4-diaminoquinazoline derivatives which are used as potentiators of chemotherapeutic agents in the treatment of cancer.

WO1992/020642 discloses bis mono- and bicyclic aryl and heteroaryl compounds which inhibit EGF and/or PDGF receptor tyrosine kinase.

EP520722, EP566226, EP635498, EP602851, WO 1995/019774 and WO 1995/15758 relate to reversible EGF receptor tyrosine kinase inhibitors. These inhibitors belong to the family of aryl and heteroaryl quinazoline derivatives and some exhibit a high inhibitory activity against EGF receptor tyrosine kinase. However, in animal pathological models these inhibitors exhibit low activity. The reason for this lies in that PTK is a catalyst catalyzing a phosphate group to transfer from ATP to a protein tyrosine residue, and the above-mentioned reversible EGF receptor tyrosine kinase inhibitors compete with ATP to bind EGF receptor tyrosine kinase, but in cells the ATP concentration is much higher (mM grade). Thus, the reversible EGF receptor tyrosine kinase inhibitors exhibiting a high activity in vitro have difficulty functioning in pathological animal models. However, since irreversible EGF receptor tyrosine kinase inhibitors do not compete with ATP, they are expected to do better in vivo.

Irreversible EGF receptor tyrosine kinase inhibitors are known and much effort has been devoted to their development. One type of irreversible EGF receptor tyrosine kinase inhibitors features a Michael acceptor at the sixth position of quinazoline, so that a Michael addition reaction can occur between the inhibitor and cysteine sulfhydryl in the active center pocket wall of EGF receptor tyrosine kinase. Furthermore, the activity of the inhibitor has a positive correlation with the activation energy of the Michael addition reaction between the inhibitor and cysteine sulfhydryl.

As used herein the term “substituted phenyl” means phenyl substituted by one or more substituents selected from phenyl substituted by one or more halo, C₁₋₈alkyl, C₁₋₈alkoxy, carboxyl, C₁₋₈haloalkyl, C₁₋₈alkylthio, phenyl, nitro, amino, C₁₋₈alkylcarboxylamino, hydroxyl, acetyl, acetyloxy, phenoxy; C₁₋₈alkoxycarbonyl, or C₁₋₈alkylcarbonyl.

The uniqueness of the compound of the invention is clearly visualized by comparing the structure and property of the compound of Example 33 with the comparison compound A of Example 84, compound B of Example 85 and compound C.

The comparison compound C is an irreversible small molecular EGFR-TK inhibitor having the highest activity among all literature-reported compounds. At a molecular level, the EC₅₀ value of the comparison compound C against EGFR-TK is 10⁻⁷ μM, while in the same test EC₅₀ value of the comparison compound B is merely about 0.5 μM, which means the activity of the comparison compound B is five million times lower compared to the comparison compound C. The difference between the two compounds in chemical structure is merely the difference in the steric hindrance of substituted branch of the sixth position. Based on that rule, the activity of the compound of the invention should be lower than that of the comparison compound B.

However, in a test of inhibitory activity of EGFR-TK at cellular level, the activity of the compound of the invention was unexpectedly several orders of magnitude higher than that of the comparison compound B. For example, the activity of the compound in Example 33 is not only much higher than that of the comparison compound B, but also close to the comparison compound A (as shown in Table 3, 4). However, the EC₅₀ value of the comparison compound A and C against EGFR-TK is equivalent at the molecular level, which means that the activity of the compound in Example 33 is equivalent to that of the comparison compound C, and it is a million times higher than that of the comparison compound B.

It has been reported in the literature that the activity of an irreversible EGFR-TK inhibitor is ten times higher than that of a reversible EGFR-TK inhibitor in A431 animal tumor model, but that the activity of the two is equivalent at a molecular level. The compound of the present invention is proven to be an irreversible EGFR-TK inhibitor by a cellular model test (as shown in Table 5), while the high activity comparison compound A to be a reversible inhibitor in the same test, which conforms to the results of a direct test using EGFR-TK described in the literature.

The compounds of the invention also inhibit Her-2 TK, and part of the results are listed in Table 6.

The compounds of the invention show a certain degree of growth inhibition against epidermal cancer cell strain A431, colorectal cancer cell strain LoVo, breast cancer cell strain BT 474 and breast cancer cell strain SK-Br-3. A part of the test results are listed in Tables 7, 8 and 9. Some compounds have 30 times higher growth-inhibition activities against A431 than Tarceva (as shown in Table 7). Some compounds have equivalent growth-inhibition activities against breast cancer with Lapatinib (as shown in Table 8). Some have better growth-inhibition activities against colorectal cancer cell LoVo than adriamycin (as shown in Table 9).

Procedure

Cell Complete Growth Medium Preparation

Mix prepared medium DMEM and F12 in the proportion of 1:1, then add FBS to a final concentration of 10%.

Compound Preparation

Dissolved the dried compound sample with 100% DMSO to 2 mM. Then diluted the dissolved compound to 20 μM with cell complete growth medium. For further IC50 determination, made a threefold dilution from 20 μM to 3.04 nM in complete growth medium containing 1% DMSO.

Cell Preparation

Prior to the assay, cultured the A431 to logarithmic phase, and then removed medium from cell monolayers and wash the cells once with sterilized PBS. Aspriated the PBS and added 2 mL trypsin solution to cover the cell growth surface, removed 1 mL trypsin solution after soaking about 1 minute. Transferred the cell-culture plate to CO₂ incubator; incubated at 37° C. for 8 minutes to allow cells to dissociate. After the cells detached, added 4 mL complete growth medium containing FBS with pipette to disperse them off and mixed gently to obtain a homogeneous cell suspension. Aspirated some of the cell suspension to a sterilized polypropylene tube, and determined the cell concentration by counting in a hematocytometer chamber under a microscope. Adjusted the cell concentration with growth medium to obtain 2.5×10⁴ cells per milliliter.

Cell Seeding

Added 100 μL adjusted cell suspension to the 96-well cell-culture plate and occasionally mixed the cell suspension during the seeding process. After seeding cells, incubated the plate at 37° C. overnight with 5% CO₂ in the CO₂ incubator for cell attachment.

Exposed the Cell to the Compound

After the cell attachment, added 100 μL prepared compound solutions to the corresponding wells (add PBS to the ambient wells of the plate). The final compound concentrations ranged from 10 μM to 1.52 nM. Incubated the plate at 37° C. with 5% CO₂ for 72 hours in the CO₂ incubator.

MTT Reaction.

After the exposure to the compound, removed the cell culture supernatant. Then added 100 μL 0.5 mg/mL MTT solution which dissolved in the growth medium without FBS. Incubated the plate at 37° C. with 5% CO₂ for another 4 hours to allow the MTT reaction to proceed.

Detection

After the MTT reaction, discarded the MTT reaction solution. Added 100 μL DMSO to each well, and the plate was agitated on the plate shaker for several minutes to dissolve the formazan. Then, detected the absorbance at 490 nm using microplate reader.
